rekans, ada info dibawah ini mengenai gps; mustinya ini kabar baik bagi kita semua. pak Kapten, apa ada perubahan yang terasa hari-2 belakangan ini atau belum sempet melaut? kan mustinya gps yang saya bawa (2 digit) bisa lebih akurat lagi sekarang .... ditunggu kabarnya ya pak kapten ... ii. http://www.infobeat.com/stories/cgi/story.cgi?id=2566182909-5b9 U.S. To Offer Satellite Navigation By ANNE GEARAN= Associated Press Writer= WASHINGTON (AP) _ Global positioning devices used to steer cars, fly planes or find missing skiers and hikers will be given pinpoint accuracy previously available only to the military under an order President Clinton signed Monday. Until now, civilians using a U.S.-built network of satellites for navigation got a less accurate reading than the military out of fear that potential enemies could use the system to target missiles. Under the order, which took effect at 8 p.m. EDT Monday (midnight GMT), the United States no longer will jam the signal for civilian users, but can still selectively block the improved Global Positioning System over any given region at will, administration officials said. The military will still use an encrypted, highly accurate version of the system for guiding precision weaponry such as the missiles used in the Persian Gulf War and last year's Balkan air strikes. ``Police, firemen, emergency crews will now be able to respond more accurately to exactly where help is needed,'' said Neal Lane, the White House science adviser. The change will make satellite navigation devices people already own 10 times more accurate, Lane said, and will not require the purchase of new machines. The difference will mean satellite navigation can be used to track a missing person to an area about the size of a tennis court. Until now, the area of intense search would have been more like a football field. That level of imprecision was problematic in emergencies and when trying to pinpoint such things as a stranded motorist's exact location. With the less accurate system, a reading for the motorist might include both sides of a busy highway or even several different roads. The system, known as GPS, is used by more than 4 million people worldwide for everything from navigating in traffic to oil exploration. Boaters and hikers use handheld GPS devices, and similar equipment is now installed in wristwatches and in the dashboards of some cars. The market for GPS users is expected to double in the next three years to more than $16 billion annually, the White House said. The system of two dozen U.S. satellites is free, but all kinds of businesses profit from it. Commercial interests have long asked the government to loosen its hold on the most accurate GPS information, but officials said outside pressure was not a factor in the decision. The decision follows four years of discussion among the White House, Pentagon, CIA and other agencies, and the development of new technology that allows the U.S. to block certain regions while offering the improved service everywhere else. Assistant Secretary of Defense Arthur Money said the new service will be available universally at first, and would only be denied in response to a perceived threat. John Pike, space policy analyst at the Federation of American Scientists, a Washington think tank, said the United States will benefit from the continued global use of its system and the control that accrues to the U.S. military as a result. Offering the better U.S. system for free takes away some incentive for another country or consortium to build a competing system, Pike said. ``Ensuring that the U.S. is the only country with such a system and making travel safer outweighs the problem of having to jam the signal to prevent the bad guys from using it to target cruise missiles,'' he said.
